ASTM (F2506-13) CERTIFIED
EFFICIENT – QUIET – LIGHT WEIGHT
WhirlWind’s Rotax GA Series propellers (ASTM certified) are designed for LSA and S.T.O.L. type aircraft. Optimized planform shape and proprietary airfoils make this propeller efficient and very quiet in operation. The carbon fiber construction with X-Core™ ensures a safe, strong propeller with low inertia as Rotax requires. The Nickel leading edge provides superior abrasion protection and the blade’s satin black finish will satisfy the most discriminating owner.
WhirlWind’s GA blades are constructed from aerospace thermo-set composite materials, and are equipped with a full length electro-formed nickel leading edge for unparalleled durability and precise fit. These blades are light and durable, and are suitable for flying in rain and from unimproved airstrips. WhirlWind’s GA hubs are machined from aerospace grade billet aluminum.
Just installed the blades, they worked very well and gave a fantastic look to the plane.All the best, Alexandre
This long prop turned 100 ponies into 100 horses. Not to mention smooth as silk. Tail comes up instantly. Take off shortened substantially. I can’t tell you how much we value good service up here. Ken Airplane : Rans S-7 Engine : Rotax
I installed Rotax 75 on my Rans S-7 aircraft. It takes off in a shorter range and climbs steeper than any other propellers I have tried. It is smooth and shiny too. Thanks Whirlwind. Ron A. Airplane : Rans S-7 Engine : Rotax
